1 ag-mum 3 1: ym. am n 5w. J gently. 85 oth' h 'ng edges to thgfbottom 2 ofthe casingnnd, i5 adppted 1e jirits, to receive, on its upper; end, the nozzlepf an 110 ,ql dinary- Bunsenburne'r, such as isvcom manly employedin connection with Welsbatch and other incandescent gas burners,

said nozzle havin the usual gauze covered outlet 35, above w ichthe admixed gas and all burn,'and also bein provided with the usual as regulatingva vs 32.

- Sai air regulating valve is rovided with a disk-like flange 33 provide with a series of peripheral perforations 33, which are adapted'to be connected by \means of a suitable pin with an adjustable hand-piece 34 which projects through the fr nt wall of the casing opening of the air inlet to the burner may be accurately regulated The pur use of the foraminated disk 33 is to ena lo the hand-piece to' be properly attached to the means for locking the reflector to the casing,

thereis provided a guard grid, referably made of cross wires,-and having t ie general form or configuration illustrated in Figs. 1, 2, 3 and 4, in which 41 represents the horizontal wires of the grid, to which are spot welded vertical'wires 42. The outer ends of the horizontal wires are curved or bent, so as to space the face-of the grid some little distance away from the front of the casing and the reflecton. The extreme ends of the middle horizontal wire 41 are bent to provide hook-like elements havin curved ends 43, which are adapted to be slipped through elongated registering openings or slots 9 and 11', which are provided in the recessed portion 7 of the front wallof the casing 1 and the marginal flange 11 'of the reflectoxgso that the hooked ends 43 will look behind ticularly shown in Fig. 1.

the front wallof the casin {as more par-. hen assembled, the guard grid is firmly locked to the reflector and ri idly locks the reflector to. the

front wall o the casing 1, in the manner I; indicated.

To assemble .the heater shell and reflector with the casing and grid and to lock the parts securely. together, the heater .shell 20, with its accessories, is adjustably positioned with its bottom engaging the flange ring 25 and its-top held by a clamping ring or bracket 15 secured to the reflector and em- 1 and by means of which the disenga e the hooked ends 0 rod 41 rom the registering openings in the 'bracin .the up. er cap 23, the reflector is then p aced wt in the o ening in the front wall of the casing 1 an supported on the flanges 7, the curved ends 48 of the middle wire-a1 of the grid are then passed throu h the registering slots or openings 9 and 1 in the reflector and the front'wall of the casing, respectively, and the grid moved downwardly a slight distance until the hoked ends lock behind the inner face of the wall of the casing, so that the curved ends of the,horizontal wires of the grid engage the fa'ce of the flange 11 surrounding the reflector. To remove the reflector, it is only necessary to lift the rid slightly. to

g the horizontal casing and reflector, so that the grid may be removed bodily, after which thereflector and the heating shell carried thereby ma be lifted out bodily, or the heating shel alone removed.

If desired, the casing may be made of a single sheet of metal pro erly cut and folded to box-like form, with t e legs formed integrally therewith, the meeting edges of the cut sheet being suitably united by spot welds or -other appropriate means. For con- 'venience of transport, the casing is provided with a handle 8 attached to the top thereof.

What I claim is 1 1. A heater comprising a casing, a burner, a foraminous shell. above the burner, a reflector inclosing the shell, and a guard dis posed in front of the reflector, said guard ving means for locking the reflector to.

the casing.

2. A heater comprising a casing, a reflector mounted in the casing, a heating unit inclosed b the reflector, and a grid in front of tlie .unit and reflector, said grid having means for locking the reflector to the casing.

3. A heater comprising ano en-fronted casing, a reflector mounted in t e opening and extending into the casing, and a guar grid extending over the front of. the-reflector, said grid having means for looking the reflector to the casing.

4. A heater comprising an o emfronted casing, a reflector mounted in te opening and extending into the casing, sald reflectorand casing having registering openings. in the forward sections thereof, and a grid extending over the front of there ector and having hooked ends engaging the registering openings to lock the reflector to the casing.
